I wouldn't hesitate to defend myself with a butter knife... but hey why use junk ?

What is your definition of "junk"? Just because a rifle is built to certain minimum specifications does not necessarily make it better. While some of the specs can lend themselves to added durability with hard use others may make absolutely no difference. It can have faulty craftsmanship and quality control like anything else, even though it isn't supposed to. Anything that is man-made and can and will fail at times, especially if placed in the hands of a sufficiently talented individual. A supposedly good top tier rifle that hasn't been maintained is no better than than a lower tier rifle that has been properly maintained and checked out. Any weapon intended to serve as a personal defense firearm needs to be gone over and shot enough to verify that it performs up to it's intended expectation regardless of make or model. That said I have seen people carry pistols for self-defense without ever having shot the pistol. I would want to run a few hundred rounds through anything I planned on using for self-defense for a general reliability check before I depended on it for anything past recreational use. I have seen and read as many reports on problems with top tier rifles as I have so called lower tier rifles, every manufacturer seems to have their teething problems at times, granted some more than others.

I am searching for cheap 308 ar manufacturers in my area. My primary aim for buying. 308 rifles are to shooting in forest as there is no certain limitation for range but 200 meter would be fine Deer and hog hunting are in my main list as they destroyed our crop field which we made us to suffer in loses.

First... few name brand companies make their own parts....The most important parts are the barrel...the BCG....and receivers...Barrel companies make them for almost all the Mfg`s...forgers make uppers and lowers for most of the companies...and BCG are made by about 4 companies for most companies....also trigger parts

So no matter what you hear most all the guns are assembled from parts from major parts houses....there are a few exceptions....Guns in the $2000 and up the high end AR`s have some good guns but good for what...If you are punching paper and shooting varmints or home defence you don`t need to spend $2000+ for a AR...$800 to 1200 will do it very well..

If you are a serious competition shooter or in law enforcment...or a few others then spending $2000+ may be in order or of coarse if you have money to burn counts also....
